I am optimizing and validating the code of our website and I am using the html validator from w3c.

I think, sincerely, which there is an error on W3C html validator.

Validating http://cpmarianobenlliureelx.cult.gva.es/marianobenlliure/index.htm


It says
   Error Line 12, column 6: end tag for "HEAD" which is not finished ..
 </head>

   (...)

But the tag HEAD is finished!!!

Here is the piece of the html code:
All between <head> and </head> is fully compliant with html4 transitional

<head>
    <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
    <meta http-equiv="Content-Language" content="es">
    <meta http-equiv="Page-Exit" content="revealTrans(Duration=0.6,Transition=12)">
    <link rel="stylesheet" type="text/css" href="../style.css" title="MainCSS">
    <link rel="alternate stylesheet" type="text/css" href="../style_large.css" title="Mayus1">
    <base target="_blank">
    <script language="javascript" src="../cpmbtxt.js" type="text/javascript"></script>
</head>

(...)

Anyone can help? Thank you.
